METHOD OF MANUFACTURING METALLIC THIN-WALL PRODUCTS WITH RAISED PROFILE AND PERFORATION Russian patent published in 1998 - IPC

FIELD: galvanoplastics. SUBSTANCE: master form is manufactured with nonmetallic holes' topology corresponding to product perforation. Over the metal layer, topology of product relief is additionally applied, the two topologies being applied with calculated anticipated distortion taking into account conditions of building up metal layers in galvanoplastic process. Several different metal layers with specified thickness can be deposited. Products with multilevel profile are manufactured from master form made on the basis of a dielectric material coated with metal layer which is selected using closed circuits over the level-change lines to the width of silting of lines during building up corresponding levels. Topology of holes can be applied with calculated anticipated distortion using chemically stable paint of dielectric material, after which uniform metal layer is deposited to the paint layer thickness, from which relief topology is applied with paint to be removed after one more metal layer is deposited. EFFECT: enhanced efficiency of deposition. 3 cl, 2 dwg
